A review of protein engineering for the food industry

In this review I briefly describe the technique of protein engineering and indicate how the present state of knowledge allows proteins to be mutated to increase or decrease stability. I discuss experiments on both model proteins and those of relevance to the food industry and show how hydrophobic forces are a major driving force for folding as well as having a major role in thermostability, I also indicate the large contribution that hydrogen bonding, electrostatic interactions and, in a less well predicted way, disulfide bridges make to thermostability.
